There are many different reasons why the screen may reman dark. If you see a message 'no signal.Going to power saving mode', the screen itself is working, but perhaps no cable connected, might be the display is just not set to be active in Windows. If one type of connection (HDMI,DVI,VGA,DP) works and the other not, that could a a faulty cable, graphics card problem - it could also be a faulty component in the tablet.

This didn't happen to me once, it happened to me twice! To reiterate the symptoms:Everything works apart from the display:- No "Wacom" logo- No power saving mode message- No LCD light leaking- Cintiq monitor is not detected on Display Port, however...- Cintiq monitor is detected on HDMI

Weird symptoms (before the Cintiq screen died): The screens would flicker every time I switched the Cintiq on or off. This seems to be related to issues with nVidia's implementation of Display Port although I wouldn't bet my Cintiq on it.

Just before the screen died, I had major corruption of the image, something similar to what a flat screen looks like when you've smashed it with a Wii controller. I switched it off straight away both times, and both times it never switched back on again.

So anyway, in both occasions Wacom has been very gracious about it. After answering the obligatory technical questionnaire, they acknowledged the fault and offered to send a refurbished replacement (only took a few days!) or get the Cintiq repaired and sent back, the latter taking longer obviously. All of this is free of charge.

I've just installed my (third!) Cintiq and all is good, apart from one pixel that insists to be red regardless of what's displayed. Still better than 2560x1440 dead pixels anyhow.

Also I can't switch to 10 bpc in the nVidia Control Panel, which is weird.

Last thing: Customer Services (who might not speak on behalf of Wacom Europe GmbH) told me they weren't aware of any issues to do with Display Port and/or incompatibilities with nVidia hardware.

Hi,

Yesterday my Cintiq 27QHD has the same issue with the screen. After few hours of use, the screen just turn black. I tried connecting in other computers but the screen was always black. I live in Argentina, the support here doesn't exist, and the price is the double because local taxes, so I'm very desperated!!

Hello, I'm a Brazilian film director and animator.This week, my Cintiq 27QHD had the same problem with the screen.I had already sent for maintenance three times because of other defects. The first time was the pen that did not work and the express key was also not working. The second time the screen turned blue after returning from maintenance. The third time the screen again turned blue. I sent it back for maintenance, and this week the tablet arrived. I used it for a few hours and suddenly the screen turned black, not even the WACOM logo appears when I turn on the tablet. I am very disappointed with the equipment, I have never, in 20 years of working as animator and film director, I dealt with such expensive equipment and so problematic ...

The Wacom has had very light use in this time, but has suddenly developed a major fault.

I went to use my computer a couple of weeks ago, and the Wacom had a flickering unstable image. After re-seating the AV cables the image stabilised for a short period of only a few minutes before flickering again, and showing Red/Green/Blue vertical lines down the screen. After resetting the computer, the screen worked again briefly before going completely blank - there is no picture whatsoever, and so the device cannot be used at all - either as a display screen or as a graphic design drawing tablet.
